RAILWAY REPAIR-CAR.

SPECIFICATION forming part of Letters Patent No. 721,856, dated March 3,1903.

Application filed November 29,1901. Serial No. 83,980. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE L. BENDER, a citizen of the United States,residing in'the city and county of San Francisco, State ofOalifornia,haveinvented certain new and useful Improvements in RailwayRepair-Oars; and I do hereby declare the following to be a full, clear,and exact description of the same.

The present invention relates to an improved railway-car designed forusein connection with the work of repairing or improving the road-bed ofthe road, such as the removal or insertion of new ties and tie-plates,the object of the invention being to provide a car carrying meanswhereby the work of replacing the tie-plates, releasing the rails,-

and holding the ties during the work of attaching the rails may befacilitated, the same consisting in the arrangement of parts and detailsof construction, as will be hereinafter set forth and described.

The invention also resides in means for actuating the power mechanism,so as to exert pressure upon the cylinder-pistons on each stroke thereofand for controlling the movement of the pistons as to speed.

To comprehend the invention, reference should be had to the accompanyingsheets of drawings, wherein Figure 1 is a side view in elevation of thecar, one of the pistons of the power means being illustrated connectedto lift the rail or release same from its tie and the tie held againstupward movement. Fig. 2 is a top plan view of the car and its mechanism.Fig. 3 is a cross-sectional end view taken on line a: 00, Fig. 2, one ofthe cylindersbeing in sec' is a broken detail view of the extension-barillustrated in Fig. 4 of the drawings.

In the drawings, the numeral 1 is used to indicate a flat-car of properlength. The platform of said car is cutaway at its center to provide aspace or passage-way 2, through which the stems 3 of the pistons 3 work.In the present case two pistons are employed, each working within acylinder 4 4. These cylinders are bolted to cross-beams 5 6 by bolts 7,their position being such that the piston-stems 3 come directly over therails 8 9. The cross-beams ,5 6 are bolted to the platform of the car,so as to be immovable. However, the cylinders are made adjustable towardand from each other by means of the screw-rod 10, which connects withthe base of each cylinder. This screw-rod is operated to adjust thecylinders by the wheel 11, which in the present case is designed to beturned by a hand-rod (not shown) fitted within the sockets 12 of thesaid wheel. By means of this adjustment of the cylinders the position ordistance between the pistons may be readily changed, so as to adapt thecar for use in connection with a narrow or a broad gage road. One car isthus capable of use in the repair of either style of road, it only beingrequired to change the trucks 13 for this purpose. The expense ofbuilding two complete cars is thus avoided.

The car as illustrated is designed for a broad-gage road. To convert itinto use for a different-gage road, the broad-gage trucks are removedand trucks of proper gage attached to the car. The bolts 7 are thenreleased and the cylinders 4 4' moved toward each other until thebolt-holes register with inner bolt-holes 14 in the cross-beams 5 6.When in this position, the piston-stems 3 will be properlyspaced to comedirectly over the rails of a narrow-gage road-bed. The bolts 7 are thenreinserted and screwed up.

The means for operating the pistons 3, so as to impart vertical movementthereto, will be hereinafter fully explained.

In case it is desired to raise the track and tie-plate clear of a tie,so as to replace either a tie-plate or a tie, the car is first broughtinto such a position as to place the pistonstems directly over the rails8 9 to one side of the respective tie. A cross-plate 15 is then placedbeneath each rail, and to the projecting ends thereof the link 16 isfitted. The opposite connected link 17is fitted over stud IOC 18,projecting from each side of the pistonstem heads 19. The rail as thusconnected to the piston-stem head is ready to be drawn upward and awayfrom the tie the moment the pistons are forced upward. To prevent thetie 20 moving therewith and to hold the tie down, a pressure-block 21 isinterposed at each side of the car between the tie20 and longitudinalbeam 22 of the car. This block fits within a socket 23, out in the sidebeam 22, so as to prevent its displacement. In this manner the tie isheld down while the railis being forced or drawn upward to release sameand its tie-plate therefrom. The upward stroke of pistons 3 issufficient to raise the rails such a distance as to withdraw retainingspikes 24 from the tie. As thus released either a new tie plate orplates may be inserted between the rails and tie or the tie withdrawnand a new tie substituted. If it is desired simply to raise the tie forany pu rpose-say to level the road-bed-the plates 15 are placed beneaththe ends of the tie instead of beneath therails. Being connected to thepiston-stem heads, as before described, the tie may be readily raisedany desired distance and so held until the earth has been tamped beneathsame. To attach the rail and tie-plates to the tie, there is employedextension-bars 25. The lower end of each extension-bar is cut away orgrooved, so as to straddle the rails in order to bear upon the head ofthe spikes 24, the upper end of each extension-bar fitting beneath thehead 19 of piston-stems 3. As the piston stems are forced downward theextension-bar bears against the spikes 24 and gradually forces same intothe tie until the flanged heads bear firmly against the flange of therails, thus attaching the rails and tie-plates to the tie. Inasmuch asthe pressure of the pistons in this case is downwardly exerted, itbecomes necessary that the tie be held against movement, so as to offerproper resistance to the piston. To accomplish this, each end of the tieis held by means of the chains, bands, or straps 26, passed thereunder.These chains, bands, or straps are secured to the studs or projections27 of the cross-beams 5 6. As thus secured the downward strain placedupon the ties is transferred to the car-plat form and the tie heldagainst movement.

It is desirable that the car be held locked or anchored against movementduring the operation of repair-work. For this purpose anchors or drags28 are provided for the rails. These anchors or drags are connected totoggle-rods 29, which rods are pivoted to levers 30, fulcrumed to eachcorner'of the car. The shanks of anchors or drags 28 fit or straddle thehead of the rails at each end of the car. To tighten the same to therails, the levers 30 are thrown downward, so as to straightentoggle-rods 29, which tilts the anchors or drags and causes same to biteupon the rails. The car is thus held locked in proper position to therails and end movement thereof prevented. Throwing the handlever 30outward loosens the anchors or drags. However, any suitable form ofmechanism may be employed to hold the car locked to the rails in casesuch is found necessary.

Any suitable motor-vehicle may be employed to operate the pistons 3, soas to impart vertical movement thereto, such as steam, compressed air,water, or other fluid. However, I prefer to utilize water for thispurpose. To do so requires that a water-reservoir and pressure-pump (notshown) he provided.

The stem 3 of the pistons work through stnffing-boxes 31, attached tothe lower end of the cylinders 4 4'. An annular passageway 32 existsbetween each piston-stem and the inner wall of its cylinder, with whichconnects a water-pipe 33. This pipe communicates with the water-supplypipe 34, which pipe connects with the valve-cylinder 35. Within saidcylinder works the verticallyinovable valve 36, the stem 37 of whichconnects with fulcru med lever 38. The body portion of the valve 36 iscut away, so as to leave an annular passage-way39 between said bodyportion of the valve and the casing 40, fitted within the cylinder 35,within which the valve works. The water from supply-pipe 34 flows intothis annular space or passage-way 39 through perforations in the casing.The flow of water from the annular passage-way into outlet-pipe 41 iscontrolled by the movement of valve 36. If the valve is raised, theupper end portion 42 thereof is carried or lifted off of its seat 43 andcommunication is established between passage-way'39 and outletpipe 41.This outletpipe connects with cylinders 4 4 above the pistons 3.Consequently the moment the valve 36 is raised to establishcommunication with outlet-pipe 41 water under pressure enters saidcylinders through pipe 41 and forces the pistons 3 downward. It will beunderstood that the valve 36 is raised by throwing the hand-lever 38upward. The moment the water-pres sure upon the pistons is out ofi bythrowing the hand-lever 38 downward, so as to reseat portion 42 of thevalve and close communication with outletpipe 41, the pistons 3 areforced upward within cylinders 4 4'. This upward movement of the pistonsis due to the pressure of water admitted through pipe 33 intopassage-way 32. The water admitted into this passage-way under pressurebears against the under face of the pistons 3 and forces same upward.The reseating of collar 42 by the downward movement of valve 36 openscommunication between outlet-pipe 41 and chamber 44 of cylinder 35. Asthe pistons 3 are moved upward by the pressure of water entering intopassage-way 32 the water resting thereon is forced back through pipe 41into chamber 44, from whence it escapes through exhaust-pipe 45. Byconnecting this pipe with the water-reservoir the exhaust-water may beused over again. The

rapidity at which the pistons are driven depends entirely upon the feedof water thereto.

ment will be imparted to the pistons. As to the power, this iscontrolled by the water-' pressure. Water-pipe 33 is provided with anysuitable form of valve 46, by which the flow of water into passage-way32 is controlled. In order that the cylinders 4 4 may be adjusted towardor from each other, as before described, it is preferable that the pipeconnections be made in sections. By such construction the same may bereadily shortened or lengthened. Still, if desired, a flexible sectionmay be interposed between the pipe connection, so as to permit of therequired adjustment. Upon the downstroke of the pistons the Water withinpassage-way 39 is forced back into water-supply pipe 34 through pipe 33.
